On May 13, 1888, Inge Lehmann was born in Copenhagen, the Danish capital. He is Alfred Lehmann’s son. He has a psychologist for a father. Ida Sophie, his mother, is a stay-at-home mom. They are one of the elite families in the nation.
She had a quiet upbringing. Over the course of her lengthy life, she remained shy. Inge began her academic career at Falleskolen, a special education institution. Boys and girls attended this school equally, studied the same subjects, and participated in the same sports and extracurricular activities, which was unusual at the time. Compared to other schools at the time, discipline of the students was not as strict.
Inge Lehmann has significantly improved throughout her time at Falleskolen in almost every area of her life. She passed the entrance exam and was accepted to the University of Copenhagen in 1906. In 1907, Lehmann enrolled in physics, chemistry, and math classes at the University of Copenhagen. In 1920, she received a degree from the university in mathematics. She began working as an assistant in the University of Copenhagen’s actuarial department in 1923. In 1925, she changed her study focus and began working with Professor Niels Norland.
She discovered that earthquake data can be used to understand the internal structure of the earth. In order to learn about methods for analyzing earth movements, she traveled to earth stations in Germany, the Netherlands, and France. In his new academic field, Lehmann has had great success. She graduated with a master’s in geology in 1928. Lehmann was given the position of Head of the Seismology Department at the Royal Danish Institute of Geodesy in 1928. He was in charge of running the observatories for seismic activity in Copenhagen, Ivigtut, and Scoresbisund.
He worked in administration. She has, however, dedicated time to scientific study, which includes enhancing the coordination and evaluation of measurements obtained from Europe’s seismographic observatories. These studies made sure that it was possible to compare and interpret data from observatories more effectively. The measurement and estimation of Lehmann’s later discoveries were made easier by the increase in measurement reliability under his direction.
Scientists began to realize that seismographic data from earthquakes could be used to understand the types of things the Earth’s inner layer was doing when Lehmann received his Master’s degree in 1928. They were aware that earthquakes cause earth to vibrate. Richard Oldham examined seismic waves from numerous earthquakes in 1906. He came to the conclusion that the Earth had a substantial, liquid, metallic core. According to calculations, this core accounts for 40% of our planet’s radius.
Seismologists were still unsure of the significance of the data collected at the observatories despite Oldham’s discovery of the Earth’s mining center. In 1936, Lehmann published his research under the straightforward title P Waves in a newspaper. Within a few years, the scientific community had come to accept the new theory regarding the internal makeup of the Earth. As more and more precise seismic measurements were made, confirming Lehmann’s work, the solid core gradually gained full acceptance.
The solid core was discovered by Inge Lehmann. In recognition of his fruitful research, he received the Tagea Brandt Prize in 1938, the Danish Geophysical Society Award in 1941 and 1944, the President of the European Federation of Seismology Award in 1950, the Emil Wiechert German Geophysical Society Award in 1964, the Royal Danish Society Gold Medal Award in 1965, and the British Royal Society Award in 1969. In 1971, he received the William Bowie Medal, and in 1977, he received the Seismological Society of America Medal.
The notion that our planet’s metallic interior is merely a molten liquid was refuted by Inge Lehmann. She conducted a mathematical analysis to determine how earthquake energy would move to the earth’s surface. Inge Lehmann is notable for having lived 104 years, making her one of the longest-living scientists in history. Inge Lehmann Medal for Outstanding Contribution to Understanding the Structure, Composition, and Dynamics of the Earth’s Core was awarded by the American Geophysical Union in 1997. winners of upcoming new studies will receive awards.
At the age of 104, Inge Lehmann passed away on February 21, 1993. Lehmann, who was married but had no children, left the Danish Academy his entire fortune.
